Transparent Display Panel Layout With Separated GIP Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The boundary between tiled display panels is visible due to gate-in-panel (GIP) circuit parts and signal lines in non-display areas, and the transmissive area is reduced in transparent displays when the gate-in-array (GIA) scheme is applied, leading to reduced transparency and increased bezel area.
Innovation Solution
The GIP circuit parts are disposed in a separate panel part from the pixel-containing panel part, with link lines and signal lines overlapping to minimize the transmissive area reduction and increase the display area, allowing for improved transmittance and reduced bezel area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GIP circuit parts are disposed in the non-display area, then the gate driver function is achieved, but the boundary between tiled panels becomes visible
Solution Approach 1:
The patent divides the display panel into separate panel parts, with GIP circuit parts disposed in one panel part and pixel parts in another. This segmentation allows the gate driver function to be achieved while the pixel parts can be tiled without visible boundaries, as the GIP circuits are isolated in dedicated regions.
Solution Approach 2:
The patent utilizes the vertical dimension by stacking multiple panel parts (first panel part with GIP circuits, second panel part with pixel parts) in the thickness direction. This three-dimensional arrangement allows gate driver functionality to be achieved without occupying horizontal display area, enabling seamless tiling in the horizontal plane.
2Shape
If GIP circuit parts are disposed in the display area, then the boundary visibility is reduced, but the transmissive area is reduced and transparency decreases
Solution Approach 1:
The patent segments the display panel into distinct functional regions: first panel parts containing GIP circuit parts and second panel parts containing pixel parts. This allows the GIP circuits to be positioned in dedicated areas without encroaching on the transmissive display area, maintaining both boundary invisibility and high transparency.
Solution Approach 2:
By arranging GIP circuit parts and pixel parts in different panel parts stacked in the thickness direction, the patent moves the gate driver functionality to another dimension (vertical stacking), freeing up the horizontal transmissive area while still achieving the gate driver function.
3Reliability
If link lines and signal lines are arranged separately, then the electrical connection is established, but the transmissive area is reduced
Solution Approach 1:
The patent merges the functions of link lines and signal lines by having them overlap in the vertical stacking direction. The first panel part contains link lines that electrically connect to the second panel part, while signal lines are disposed in the second panel part. This combined arrangement establishes electrical connections while minimizing the horizontal area occupied by wiring.
Solution Approach 2:
The patent resolves the wiring area conflict by utilizing the vertical dimension - link lines in the first panel part overlap with signal lines in the second panel part in the thickness direction. This three-dimensional wire routing allows electrical connections to be established without increasing the horizontal transmissive area.

AI summary
Disclosed is a display apparatus in which a GIP circuit part is disposed in a panel part separate from a panel part including a pixel, such that decrease in a size of a transmissive area of the panel part including the pixel due to the GIP circuit part is minimized. Thus, a transmittance of the display apparatus embodied as a transparent display apparatus may be improved.
